MasterBind USA Binding Machine system is different than anything out there. They have a proprietary system for binding using channel spines for binding. The channel system is a metal spine to hold your documents. You just place your paper in the spine. Put them in the binding machine and pinch together. The documents will not move.
MasterBind USA Binding Machines are heavy duty and reliable. There are 150 sheet capacity and 300 sheet capacity machines.
They have a large variety of covers and options. You can create custom covers using a pouch lamination system. Choose leather covers and spines for high-end document creation. If you are in sales, accounting, a law firm, you may find these more to your style. They also offer foil stamping machines for custom cover printing.
MasterBind is a different approach to bookbinding that is entirely customizable to what you may need or want to offer your customers.
